We present a rare case of cystic cervicitis in 42-year-old woman who came to our unit suffering from primary infertility for one year. Her only complaint was infertility. She not chronic pelvic pain or increased vaginal discharge neither before nor after marriage. Diagnosis made by both transvaginal ultrasound examination and MRI. As her main problem infertility, she refrained doing cone biopsy...
The complexity of the mechanics involved in the mammalian reproductive process is evident. Neither an ovum nor an embryo is self-propelled, but move through the oviduct or uterus due to the peristaltic action of the tube walls, imposed pressure gradients, and perhaps ciliary motion. Here we use the method of regularized Stokeslets to model the transport of an ovum or an embryo within a peristal...
Growing mouse oocytes and fertilized ova were injected with chicken ovalbumin messenger RNA (mRNAov) and chicken conalbumin mRNA (mRNAcon) and cultured in vitro. Estimation of mRNAov and mRNAcon stability by hybridization of cDNAov and cDNAcon to extracted mRNA from injected oocytes and fertilized ova indicated a half-life of 147 and 366 h in the oocyte and 5 and 3 h in the fertilized ovum resp...
We have analysed the content of the growth and differentiation regulating peptide, transforming growth factor beta1 (TGFbeta1), in follicular fluid from patients undergoing in-vitro fertilization (IVF), and correlated concentrations of TGFbeta1 with the outcome of the IVF treatment and the concentrations of 17beta oestradiol in serum at ovum retrieval. A total of 88 women with infertility of >3...
To determine whether there is a relationship between oviposition time and the release of spermatozoa from the uterovaginal junction-sperm-host glands (UVJ-SHG), oviducal segments from turkey hens were isolated and washed immediately or 8-12 and 18-22 h after oviposition on Days 1, 2, 3 and 10-13 after artificial insemination. Spermatozoa were found in nearly all segments at all times examined, ...
The female reproductive tract is commonly referred to as oviduct in birds. The oviduct is a highly convoluted muscular duct, concerned with the transport of the ovum away from the ovary, with fertilization of the ovum and by the deposition of albumen, membranes and shell on to the ovum to form the finished egg [1]. Reproductive diseases in poultry causes high morbidity (35%), mortality (15%) an...
A large Schistosoma mettheei ovum containing two miracidia was recovered from a squash preparation of the liver of an experimentally infected hamster. When observed, the miracidia were motile and facing in opposite directions.
In this controlled clinical study, we determined the serum and follicular fluid concentrations of the biologically active fractions of magnesium (Mg) and calcium (Ca) in 39 women undergoing controlled ovarian stimulation (COH) for in vitro fertilization (IVF) embryo transfer (ET). Serum levels of ionized Ca (Ca2+) and ionized Mg (Mg2+) were measured during day 3 of the IVF cycle, on the day of ...
